Application filed October 31, 1918.

To all whom it may concern:

Be it known that I, RAoUL J. GRUErIBERG, a citizen of the United States, residlng at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Sifter-Top Carton, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a sifter top carton and its object is to produce a sifter top in connection with an ordinary paper or fiber board box.

It will be understood by those skilled in the art that the material of which the common paper board boxes are made is not of such a character as to permit the production therein of small enough holes to be satisfactory for sifting out spices so that where such small holes are necessary, I use a layer of stencil board or other suitable material in which the holes are punched, these holes being covered when the package is shipped or sold to the consumer nother object of the invention relates to the closure of the holes in such manner as to enable the housewife to easily open them when she desires to use the contents of the package.

Other-"objectspo-f the invention-Mill appear as the description proceeds.

An embodiment of the invention is shown in the drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Figure 1 is a perspective view of a box having this top applied thereto and ready for use, m.

Fig. 2 is a perspective view of a slightly modified form of the box, partly open, and

Fig. 3 is a plan view of the sifter memberalone, a portion of the Sifter holes cover being removed.

The numeralv 1 indicates any form of paper board carton having end flaps 2 and 4 between which flaps is a layer of a hard stencil board 3 in which the sifter holes are punched. The member 3 may be of any suitable material but it is essential that the holes be covered duringthe time .the package is passing from the manufacturer to the consumer and this is accomplished b roducing a sheet of material of the esired hardness and toughness and then coverin it with a translucent cover 6 which will t en show the holes and which holes may be Specification of Letters Patent.

easily punctured by the user. The punched slfter member is then secured in place between the two end flaps of the carton and since they each have holes in register as shown in the flap 4 the carton may be used whenever desired.

In Fig. Zthereis shown a carton 9 which has end flaps 10 and 12 between which the sifter flap 11 is secured The holes in the sifter flap are in the position of two registering holes in the flaps 10 and 12 and are temporarily covered by the partly cut portion 13 of the end flap12, said portion 13 having a tab 14 to open it with. As shown in Fig. 2, the cover portion 13 has been partly pulled up by the tab 14 to expose some of the holes in the member 11. It will be understood by those skilled in the art that the cover 13 is deep scored or cut so that it is easlly removable when necessary, and is only used where additional'protection for the transparent shield is required.

The sifter flap may be made of any suitably hard and tough material in which clean small holes can be produced.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is as follows, express reservation being made of permissible modifications.

1. A sifter top box comprising a paper or fiber board box having end flaps with openings therethrough, a perforated sifter flap of substantially the same area as the box secured to the end flaps so that its Sifter openings will register with the end flap openings, and a translucent cover for temporarily closing the sifter openings.

2. A sifter top box comprising a paper or fiber board box having end flaps formed with openings therein, a perforated slfter flap of hard material secured between the end flaps so that the sifter openings therein will register with the end flap openings, and a translucent material secured to the sifter flap for temporarily closing the openings therein.

3. The combination with the end closure flaps of a carton having registering openings therein of a separate foraminous wall, and a translucent seal for closing said foraminations in the end of the carton.

In testimony whereof I have hereunto set my hand this 22nd day of October, A. D 1918.

RAOUL J. GRUENBERG.
